Rename function used to print absolute paths.
    
    - Previously, the tcar_checkWorkDirSource function was used to print
      absolute paths from non-option arguments retrieved from the
      command-line. The name of this function intents to describe its
      initial purpose, however, it has a wider use inside tcar automation
      scripts. So, in order to better describe what this function does,
      this update renames the tcar_checkWorkDirSource function to
      tcar_printAbsolutePath.
    
      Path cleanup is already done inside the tcar_printPath function
      which is called from tcar_printAbsolutePath.
